What does CPM stand for?

CPM is a fairly stan­dard unit of mea­sure in the online adver­tis­ing business.

It stands for Cost per thou­sand (the M is the Roman numeral for 1,000). What it’s mea­sur­ing is the cost per thou­sand ad impres­sions.

Take heisel.org for exam­ple. For the month of Novem­ber I had a little more than 1,000 page views. If I sold ads, and if I sold them at a $5 CPM, then I’d have roughly $5 in rev­enue for the month.

A simple number that belies even more to talk about, but I’ve got a tree to dec­o­rate, so that’s all for tonight.
